    Abstract
    Aus der Benutzung der Universitätsbibliothek Ulm wurde eine Halbwertszeit-Funktion in der naturwissenschaftlichen Literatur von t1/2=5 Jahren bestimmt. Eine interessante Abweichung von dieser Halbwertszeit-Funktion ist bei der Bestellung der neuesten Zeitschriften zu beobachten. Der Grund hierfür liegt vermutlich darin, daß Wissenschaftler das Vierfache an neuester Literatur lesen müssen, um wissenschaftliche Trends zu überschauen. Eine weitere Abweichung ist in der ältesten Literatur festzustellen, bei den sog. 'citation classics'. Übereinstimmung zeigt sich im Zitier- und Kopierverhalten bei Zeitschriftenliteratur, die älter als 2 Jahre ist. Etwa 27% der an die UB Ulm gerichteten Literaturanforderungen betreffen Zeitschriftenaufsätze mit einem Alter von über 10 Jahren, da diese Bestände für die Benutzer nur schwer zugänglich sind. Dies zeigt die große Bedeutung einer Freihand-Bibliothek

    Abstract
    Q-analysis is a methodology for investigating a wide range of structural phenomena. Strutures are defined in terms of relations between members of sets and their salient features are revealed using techniques of algebraic topology. However, the basic method can be mastered by non-mathematicians. Q-analysis has been applied to problems as diverse as discovering the rules for the diagnosis of a rare disease and the study of tactics in a football match. Other applications include some of interest to librarians and information scientists. In bibliometrics, Q-analysis has proved capable of emulating techniques such as bibliographic coupling, co-citation analysis and co-word analysis. It has also been used to produce a classification scheme for television programmes based on different principles from most bibliographic classifications. This paper introduces the basic ideas of Q-analysis. Applications relevant to librarianship and information science are reviewed and present limitations of the approach described. New theoretical advances including some in other fields such as planning and design theory and artificial intelligence may lead to a still more powerful method of investigating structure
